High Availability Data Center Back-up Power Schemes
Learning Objectives:
- Describe the interrelationships of reliability, redundancy, and availability.
- Identify the fault tolerance implications of redundancy schemes: N, N+1, 2N, and 2(N+1).
- Explain the various data center availability ratings: levels 1-4.
- Explore how intelligent management of multiple-generator back-up power schemes can increase availability and autonomy, minimizing exposure of down-time during a utility outage.

Our society has become highly dependent on electrical power. It is the underpinning of virtually everything we take for granted in everyday life at home, work and in many cases, public transportation. Moreover, virtually all of the critical infrastructure for communications, security, as well as emergency services and life safety depend on power.
Moreover, in the Internet age of the digital economy, mobile computing, and cloud based services, as well as increased dependence on digital records by emergency services and health care providers, have raised the availability bar for 7x24 of data centers.
Climate change in general and the record weather extremes will continue to increase the likelihood of utility power interruptions, as well as risks to life and property. In this new age, 100 year events are becoming common, making it clear that essentially no place is totally immune to natural risks. Therefore, reliable back-up power has become as important as primary utility service for data centers.
While the basic concept and need of the back-up power systems has not changed, the increased availability requirements for mission critical back-up power systems for data center and telecommunication systems has become more important than ever.
This webinar will discuss the key aspects of high availability power schemes for data centers and how they meet the various requirements and issues related to supporting critical IT equipment and cooling system loads.
In this part of our series of webinars, we will examine the considerations when specifying and selecting power systems for data centers.
